Sleeping pills and a bottle of wine were found near the body of a 39-year-old schizophrenic man who police believe committed suicide, officials said Tuesday.

County workers spotted the man lying on a sleeping bag near a riverbed east of Bluff Road and Mines Avenue on Monday. When they went back to check on him at about 4:53 p.m. Monday, they noticed he slipped off the sleeping bag and onto the concrete and called police, Montebello Lt. Michael Bergman said.

He said the man, a local resident, had tried to commit suicide before.
